The short answer to this question is: YES! Over the last few years I've been fortunate enough to coach some really talented and smart individuals. I estimate when we first started working together as coach and athlete, 95% of these people, upon seeing the easy pace range I gave them for their easy runs, texted me to ask is this pace range a mistake. It is absolutely not a mistake. A very high percentage of runners are running their easy runs too fast and completely defying the purpose of an easy run, and not allowing your body to reap the benefits of your harder speed sessions.
It seems like such a simple concept, doesn't it? Just slow down. Enjoy the scenery. It's actually much harder than it sounds. I, too, have been guilty of zipping through my easy runs at paces that are not doing my body any good. Thankfully, last year I made the commitment during my Boston Marathon training to slow my roll and I haven't cheated since. My own observations after the training cycle was over included: better recovery from hard workouts, hitting faster paces with less effort during those workouts, and I completed the training cycle with zero feelings of burnout at any point. I'll admit it was mildly annoying to hop on Strava to look at my run details and see the "Trending Slower" in my matched runs column, but I was able to see how completely ridiculous and meaningless this was.
If my own experiences aren't enough, take a look at the elite runners you admire. Elite marathoners routinely run their easy paced runs more than two minutes per mile slower than their marathon pace. Running your easy runs at a pace truly easy for you will not make you slower. It will leave you feeling recovered and ready to hammer your harder workouts!
So I challenge you to give it shot. Ditch the ego and listen to your body. And then let me know how it goes!
